B NOTE: It take about 30 seconds for stations to become available for configuration after install-ing a new module.

ESP-ME3 Controller8

EN Station NumberingThe controller is configured with “fixed station num-bering”, meaning that Bays Two, Three and Four can accept either a 3 or a 6-Station Module. If a 6-Station Module is NOT installed then the unused stations are reserved for future use.

Example of Station Numbering when using two 3-Station Modules. A total of 10 stations are installed.

Bay One Bay Two Bay Three Bay Four

• The Base Module is installed in Bay One and uses Stations 1 through 4.

• A 3-Station Module is installed in Bay Two and uses stations 5 through 7. Stations 8 through 10 are skipped and will be unavailable.

• A 3-Station Module is installed in Bay Three and uses stations 11 through 13.

During programming, the controller will skip any unused stations, creating a gap in station numbering. The unused stations will show on the display as 8SKIP, 9SKIP, etc.

If the screen displays 20NOMOD where the 20 is flash-ing, then there is no module installed for that station number.

Complete Controller InstallationaReinstall and reconnect the front panel.

bApply power to the controller and test the system.

B NOTE: The electrical connections can be checked even if water is not available. If water is available and you would like to test some or all of your stations, use the Test All Stations feature of the controller.

EN Program-Based SchedulingThe ESP-ME3 uses a programmed-based scheduling method to create irrigation schedules. This means all stations with a run time on the program will run in numerical order.

Common Programming ErrorThe most common programming error for any pro-gram-based controller is to set multiple Program Start Times that cause watering cycles to repeat.

As an example: Program A has a 1st Start Time set to run at 8:00 AM. But then a 2nd Start Time has mistak-enly been set for 8:15 AM, which means that all sta-tions would water a 2nd time.

In this example, a 3rd Start Time has mistakenly been set for 8:30 AM. Which means all stations would water a 3rd time. The desired watering time was 45 minutes, or 15 minutes per station. The actual is 2 hours and 15 minutes, which is excessive watering!

Watering Issues

Problem Possible Cause Possible SolutionDisplay shows a program is active, but system isn’t watering.

Water source not supplying water. Verify there is no disruption to the main water line and that all other water supply lines are open and functioning properly.

Wiring is loose or not properly connect-ed.

Check that field wiring and master valve or pump start relay wiring is securely connected at the controller and in the field.

Field wires are corroded or damaged. Check field wiring for damage and replace if necessary. Check wiring connections and replace with watertight splice connectors if needed.

Loss of AC power. When there is a power loss and a 9 volt battery is in-stalled, the system does not irrigate but programs show as remaining active.

NO AC message on display.

No Power detected. Check circuit breaker and that unit is plugged into socket or properly connected to power source.

Controller may be plugged into a GFCI outlet or an outlet that is wired to a GFCI outlet.

Check power to the outlet or reset the circuit breaker.

It just rained and the alarm light is not illuminated, why?

This is normal operation. The ESP-ME3 does not consider the interruption of irrigation due to rainfall as an alarm condition.

This is normal operation.

Flow Alarms

ErrorALARM

LEDError Message

On DisplayFlow Sensor - High Flow Con-dition

Solid HIGH FLOW ALARM STA-TION "X"

Flow Sensor - Low Flow Con-dition

Solid LOW FLOW ALARM STA-TION "X"

When a flow sensor is in use the ESP-ME3 monitors for High Flow of 130% above regular learned flow. This percent limit can be adjusted in the Rain Bird App when used with LNKTM WiFi Module. If a High Flow con-dition is detected, a “High Flow Alarm” is shown at the display and the red alarm LED comes on. To clear the alarm press the “Hold to Start” right arrow button dur-ing the alarm message.

Low Flow conditions are also monitored. The limit for Low Flow is 70% below the learned flow unless changed in the Rain Bird App. A Low Flow alarm is shown at the controller display and the red alarm LED comes on.

To clear the alarm press the “Hold to Start” right arrow button during the alarm message.

B NOTE: Turning the flow sensor feature off and then back on will cause the controller to learn new flow levels and ignore previous error condi-tions.

B NOTE: If the flow sensor measures flow when the controller is not scheduled for watering, a “HIGH FLOW ZONE” alarm is shown on the display and the red alarm LED comes on. To clear the alarm press the “Hold to Start” right arrow button dur-ing the alarm message.


EN Watering Issues

Problem Possible Cause Possible SolutionProgrammed sched-ules do not start.

Connected rain sensor may be activat-ed.

Set Rain Sensor to Sensor OFF to ignore the rain sensor. If watering resumes, the sensor is operating properly and no further correction is needed.

Connected rain sensor may not be oper-ating properly.

Let the rain sensor dry out, or disconnect it from the controller terminal strip and replace it with a jumper wire connecting the two SENS terminals, or set to Sensor OFF.

If no rain sensor is connected, the jumper wire connecting the two SENS terminals on the terminal strip may be missing or damaged.

Move dial position to Weather Sensors and set to Sensor OFF.

Too much irrigation Multiple Start Times in the same pro-gram.

Separate start times are not required for each valve. A program only requires single start time in order to run all stations in that program.

Multiple programs are running at the same time.

Review programming to assure that the same Station is not active in multiple Programs.

Valve is malfunctioning. Check to see if the ALARM light on the controller is lit solid, then repair or replace the valve if necessary.

Seasonal Adjust setting is too high. Set Seasonal Adjust to 100%.

Electrical Issues (solid LED illuminated)

Problem Possible Cause Possible SolutionDisplay is blank or fro-zen, the controller will not accept program-ming or is operating abnormally.

Power not reaching the controller.

Verify the main AC power supply is securely plugged in or connect-ed and working properly.

Controller needs to be reset. Press the Reset Button. For details see “Reset Button” section.

An electrical surge may have interfered with the control-ler’s electronics.
